People also were killed by wolves in North America before the 20th century.
Bears still maul and kill people, and anyone who isn’t afraid of the big, bad bear is a fool-there is also a season to hunt bears in states where there is a big, stable population of them.
Hunting wolves in Alaska is allowed and regulated, and they have many, many more wolves than the lower 48 could hope to anytime soon.
There aren’t enough mountain lions to have a season here where I am-they are protected-nor have there been attacks on humans, unlike in California-but I see tracks often and I’ve heard them vocalizing while I’m hiking, so I carry pepper spray and don’t go sneaking around quietly. If the mountain lions ever get really numerous and start attacking people like bears do, I imagine there will be a season for them, too.
